Fibrin and D-dimer bind to monomeric GPVI [PDF]
: Fibrin has recently been shown to activate platelets through the immunoglobulin receptor glycoprotein VI (GPVI). In the present study, we show that spreading of human platelets on fibrin is abolished in patients deficient in GPVI, confirming that ...

Receptor-Dependent and -Independent Effects of Hemin on Platelet Plasma Membrane Disintegration. [PDF]
Microhemorrhages lead to the release of erythrocytes, which are then degraded and lysed. These hemolyses result in the liberation of free iron‐containing hemin. Hemin induces platelet activation and ferroptosis. Inhibition of GPVI/CLEC‐2 receptor‐mediated ITAM‐signaling inhibits hemin‐induced platelet activation (low hemin concentrations). Deferoxamine,

Platelet dysfunction in immune thrombocytopenia: Finding clinical subsets with platelet phenotypes. [PDF]
Summary Patients with immune thrombocytopenia (ITP) remain a challenge to diagnose, manage and predict bleeding risk. A comprehensive assessment of platelet function may aid clinical management. This study assessed platelet parameters to predict bleeding in ITP.

Mechanisms That Prevent Vascular Leakage During Leukocyte Extravasation. [PDF]
ABSTRACT Background Inflammation is the response of the immune system against harmful stimuli in tissues. Leukocyte extravasation or TransEndothelial Migration (TEM) is a crucial step during inflammation, in which leukocytes migrate over the endothelial barrier toward the damaged tissue.

Role of focal adhesion tyrosine kinases in GPVI-dependent platelet activation and reactive oxygen species formation. [PDF]
We have previously shown the presence of a TRAF4/p47phox/Hic5/Pyk2 complex associated with the platelet collagen receptor, GPVI, consistent with a potential role of this complex in GPVI-dependent ROS formation.

Preparation of cold-stored platelets on-demand: A novel approach to inventory management. [PDF]
Abstract Background Cold‐stored platelets (CSP) are now being used to treat acute bleeding. However, as CSP are less suitable for prophylaxis, both room temperature (RT) platelets and CSP will be required, which complicates inventory management. The production of CSP “on‐demand” from RT platelets may be a desirable option.

In Vitro Comparison of Device-Induced Hemolysis, Platelet Defects, and von Willebrand Factor Degradation Between the HeartMate 2 and HeartMate 3 Pumps. [PDF]
This in vitro comparative study demonstrated that the HeartMate 3 pump has a superior overall hemocompatibility profile to the HeartMate 2 pump, underscoring the advantages of the maglev centrifugal pump design compared to the axial pump design. ABSTRACT Background Left ventricular assist devices (LVADs) have been utilized to maintain the circulatory ...

Minimal Collagen-Binding Epitope of Glycoprotein VI in Human and Mouse Platelets
Glycoprotein VI (GPVI) is a platelet-specific receptor for collagen and fibrin, regulating important platelet functions such as platelet adhesion and thrombus growth. Although the blockade of GPVI function is widely recognized as a potent anti-thrombotic
